Book mailer

ABSTRACT

A mailer for a flat object such as a book or the like consists of a base panel having first and second cell forming panels foldably connected to each other and to opposite edges of the base panel together with closure panels foldably connected to the cell forming panels which when secured in lapping relationship define a flattened tube. End closure flaps are foldably connected to the base panel and also to the closure panels and having converging side elements at the ends thereof which register with each other when the base panel and the overlapped closure panels are separated from each other and folded into lapping relationship, the cell forming panels during such separation adopting a transverse sectional configuration corresponding to the converging side elements of the closure flaps.

3 Claims, 5 Drawing Figures BOOK MAILER THE DRAWING FIG. 1 is an isometric view of a book mailer having the improvements according to the present invention embodied therein;

FIG. 2 is a plan view of a cut and scored blank for forming the mailer seen in FIG. 1;

FIG. 3 is an isometric view showing the mailer of FIG. 1 in the flattened condition thereof preparatory to loading;

FIG. 4 is a view similar to FIG. 3 showing the mailer in erected and loaded condition preparatory to closing of the end panels; and

FIG. 5 is a transverse sectional view taken along the line 55 of FIG. 4.

The improved mailer according to the present invention for holding a book B is denoted by the reference numeral and is formed from a cut and scored blank 10A of paperboard or the like, and comprises a base panel 11, opposed first cell forming panels 12, and opposite second cell forming panels 13 these being foldably joined along a fold line 14. First cell forming panels 12 are foldably joined to opposite edges of the base panel 11 along fold lines 16. Closure panels 17 are foldably connected to the second cell forming panels 13 along fold lines 18, and these are arranged to be folded and secured in lapping relationship to define a flattened tube as seen in FIG. 3 with base panel 11 and the cell forming panels 12 and 13. End closure flaps 19 are foldably connected along fold lines 21 to opposed other sides of the base panel 11, and the ends of each have converging side elements 22.

Additional end closure flaps 23 are foldably connected along fold lines 24 to the ends of the closure panels 17 and these likewise have converging side elements 26 at one of the ends thereof, these elements being adapted to register with the elements 22 of the closure flaps 19 when the base panel 11 and the overlapped closure panel 17 are separated from each other and the closure flaps 19 and 2.3 are folded into lapping relationship.

The first and second cell forming panels 12 and 13 during the operation seen in FIGS. 4 and 5 adopt a transverse sectional configuration of the side elements 22 and 26 of the respective end closure flaps 19 and 23.

The triangular shaped cells formed by panels 12 and 13 serve to retain book B between panels 17 and 11, and provide a cushion for edges of the book.

We claim:

l. A mailer for a flat object such as a book or the like, said mailer being formed from a cut and scored blank of paperboard or the like and comprising:

a. a base panel;

b. first and second pairs of cell forming panels foldably connected to each other and to opposed edges of said base panel;

c. closure panels foldably connected to said second cell forming panels and being folded and secured together to define a flattened tube with said base panel and said cell forming panels;

d. end closure flaps foldably connected to said base panel and having converging side elements at their ends;

e. additional end closure flaps foldably connected to said closure panels and having converging side elements at one of the ends of each;

f. said first and second cell forming panels a transverse sectional configuration corresponding to the convergence of the side elements of said end closure flaps.

2. A mailer according to claim 1 wherein said end closure flaps are unsecured to said cell forming panels.

3. A mailer according to claim 1 wherein said closure panels are secured in overlapping relationship. 

1. A mailer for a flat object such as a book or the like, said mailer being formed from a cut and scored blank of paperboard or the like and comprising: A. A BASE PANEL; B. FIRST AND SECOND PAIRS OF CELL FORMING PANELS FOLDABLY CONNECTED TO EACH OTHER AND TO OPPOSED EDGES OF SAID BASE PANEL; C. CLOSURE PANELS FOLDABLY CONNECTED TO SAID SECOND CELL FORMING PANELS AND BEING FOLDED AND SECURED TOGETHER TO DEFINE A FLATTENED TUBE WITH SAID BASE PANEL AND SAID CELL FORMING PANELS; D. END CLOSURE FLAPS FOLDABLY CONNECTED TO SAID BASE PANEL AND HAVING CONVERGING SIDE ELEMENTS AT THEIR ENDS; E. ADDITIONAL END CLOSURE FLAPS FOLDABLY CONNECTED TO SAID CLOSURE PANELS AND HAVING CONVERGING SIDE ELEMENTS AT ONE OF THE ENDS OF EACH; F. SAID FIRST AND SECOND CELL FORMING PANELS A TRANSVERSE SECTIONAL CONFIGURATION CORRESPONDING TO THE CONVERGENCE OF THE SIDE ELEMENTS OF SAID END CLOSURE FLAPS.
 2. A mailer according to claim 1 wherein said end closure flaps are unsecured to said cell forming panels.
 3. A mailer according to claim 1 wherein said closure panels are secured in overlapping relationship.
